Embodiment Construction
[0027]The brush cutter 1 of the present invention, as shown in FIGS. 1 to 3, has a rotatable drum 3. The drum 3 includes a central, tubular member 5 having a cylindrical surface 7. Annular collars 9 are mounted on the tubular member 5, the collars of equal size and equally spaced-apart and transverse to the longitudinal, central axis 11 of the tubular member 5. Each collar 9 has an inner circular periphery 13, sized to just receive the member 5 there through, and an outer periphery 15. The outer periphery 15 is also preferably circular but it could also have helical sections. Each collar 9 is welded onto the surface 7 of the tubular member 5. The drum 3 is mounted at its ends in any well known manner in a frame (not shown) that carries the drum and the drum is rotatable in the frame about its axis 11 by suitable drive means, (not shown).
[0028]Each collar 9 has at least one first cutout 17 extending radially inwardly from the outer periphery 15 of the collar. The cutout 17 has a gene...

Abstract
A cutting tooth having a blade-like cutting section and a mounting section extending down from the bottom of the cutting section. The mounting section is narrower and shorter than the cutting section, and generally centered with respect to the cutting section. The mounting section has laterally extending flanges spaced from the cutting section. At least a quarter of the cutting section extends past the front of the mounting section and terminating in a cutting edge.The cutting tooth is adapted to be mounted in a mounting block to form a cutting assembly. The mounting block has a slot extending into the block from the front face, the slot open in the top surface of the block. The mounting section of the tooth slides into the slot in the block to locate the cutting section on the top of the block with the cutting section projecting forwardly of the block. The flanges on the tooth hold the tooth in place in the block against centrifugal forces. The cutting assembly is adapted to be mounted between two collars on a brush cutting drum with the cutting tooth above the periphery of the collars.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority on provisional U.S. application No. 61 / 344,453 filed Jul. 26, 2010, the entire content of which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]This invention relates to a cutting tooth for a brush cutter. The invention further relates to a cutting assembly for a brush cutter. The invention also relates to a brush cutter incorporating the cutting assembly.[0004]2. Background Art[0005]Brush cutters employing a cylindrical, rotatable, drum with cutting assemblies mounted on the drum, the drum mounted on the front of a vehicle or on a boom on a vehicle, are known. The cutting assemblies each generally comprise a mounting block fixed on the drum with a cutting tooth detachably mounted on the block. Since the mounting blocks and the teeth thereon are exposed on the surface of the drum, the brush cutters require frequent maintenance both in replacing damaged elements ...
